olivier saillard talks about Rei in here (only french listeners ! sorry !)
and a christian rizzo show ...
very interesting !
they talk about the 1997 show. anybody has pictures ? in here, perhaps.
edit : there's one up there and i see which collection now.
i didn't know she wanted to be named : "business woman" - and not artist or designer.

they talk about Margiela and Hussein Chalayan, too. and there's Chrisitian Rizzo ! It IS amazing !

PS: Does anyone know anything about Koji Tatsuno? He was a protege of Yohji's in the early 90s but got forced out of business a while ago (not sure if he started back up again, though, all I can find on him are a handful of short interviews and a New York Magazine article that mentions him)....any info would be welcome!

for the last part:
-- with the rapid change of the times, what the avant-garde creation as against the classic means is changing?

what I do has been the same. it's just that it has been talked about in accordance with the interpretation of the society or movement of each time, surroundings having been changing little by little. for example I have been wearing the rider's jacket since the 80's. my style has been the same. the way I am and things in my mind have never been changed, and I'm not going
to change them.
